Among the works dealing more especially ■with, the stratigraphy 

 of the Lower Oolite rocks of Yorkshire, reference may be made 

 to the Geological Survey Memoirs by Messrs. Fox-Strangways, 

 Barrow,^ and H. B. Woodward,'' and to a series of valuable papers 

 by Hudleston,^ published in the Proceedings of the Geologists' 

 Association, also to Etheridge's Presidential Address of 1882.* 



The second volume of the Geological Survey Memoirs on 

 the Jurassic rocks of Britain, contains a long list of fossils by 

 Fox-Strangways, who acknowledges assistance in the revision of 

 the plants by Clement Reid.' As this is the most recent list 

 of plants hitherto published, and is largely founded on the notes 

 by Nathorst to which reference has already been made, I have 

 enumerated those species from Fox-Strangways' list which are 

 referred to as "species now recognized," adding in each case the 

 names employed in the present Catalogue. A change of nomen- 

 clature has been adopted in several instances, the reasons for the 

 changes being stated in the description of each species : — ■
